lubrication system through the starter (ATS) mounting
pad and flowing through the ATS shaft and ports as
shown on Figures 1 and 2.  The AMAD/ATS pad shall be
wet with the ATS having a dry sump with a dedicated
positive scavenge connection to the AMAD. The
scavenge port on the ATS shall Include a coarse mesh
screen to prevent contaminants from entering the
AMAD.  Conditions existing at the AMAD/ATS pad to be
as follows:
Oil flow at (50%) 12,600 rpm ATS speed - 1.6 gpm
(.85 at pad, .75 at shaft)
Oil temperature at (50%) 12,600 rpm ATS speed -
180F
Oil pressure at (45%) 11,350 rpm ATS speed and
above - 40 psid
Maximum oil pressure - 280 psig
Maximum oil temperature - 250F
Maximum ATS cavity pressure - 10 psid
Minimum scavenge to supply oil flow - 2:1
The starter shall be capable of satisfactory
operation with random interruptions of oil flow of up
to 30 seconds duration.  Leakage of lubricants from
the starter shall not exceed 2 cc/hour.
Exposure Temperature Range: -100 to 245F
